FlutterFlow/flutterflow-ui ? reverse-engineered prompt

Build me a Flutter package that makes it easy to paste FlutterFlow generated UI code into a normal Flutter app.

I want it to include the common FlutterFlow widgets and helpers so copied screens and components work without a lot of manual cleanup. The package should let me replace the usual FlutterFlow imports with one simple package import, and it should support things like layout widgets, buttons, charts, maps, tabs, web view, audio, timers, toggles, and the other standard pieces FlutterFlow exports.

Please make the README clear for someone following along from FlutterFlow, with simple steps for copying widget code, adding the dependency, swapping imports, and fixing the common state and model issues that show up after pasting. If there are any setup details or current docs I should follow, look them up online and keep the instructions accurate.

I also want the package to feel polished and ready to publish, with a clean example of how a FlutterFlow widget can be dropped into an existing screen.
